European foreword
This document (prEN 16494:2022) has been prepared by Technical Committee CEN/TC 256 “Railway
applications”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 16494:2015.
This document has been prepared under a Standardization Request given to CEN by the European
Commission and the European Free Trade Association, and supports essential requirements of EU

Introduction
This document was produced for the specification and harmonization of a specific set of ERTMS trackside
boards to support ETCS and GSM-R operations.
In EN 16494:2015, ETCS and electrification trackside boards were harmonized and these were specified
in a square format only.
In this version of the document, the following changes were made:
— Clarification of Scope to exclude mobile, backlit and temporary signs;
— Dimensional corrections to the ETCS Stop Marker and ETCS Location Marker;
— New trackside boards were introduced (traction system 25 kV, 15 kV, 3000 V, 1500 V and 750 V,
audible warning device, safe stopping area, non-stopping area, inhibition of magnetic shoe brake,
inhibition of eddy current brake, inhibition of regenerative brake, close air-conditioning, open air-
conditioning, and level crossing marker);
— An option for diamond-shaped trackside boards (electrification MBs only);
— Clarification to existing maintenance requirements;
— Revision of the options for standard dimensions;
This document contains colour images for indicational purposes only.
